This research team is working out how to detect extraterrestrial cells in the liquid water ocean hidden beneath Enceladus’s icy crust.

NASA’s minivan-sized drone is scheduled to search for signs of life on Titan in 2034.

While Saturn and its moons all appear faint and cloudy to JWST, Saturn’s rings are the star of the show. Here’s the big scientific reason.

From size to mass to density and more, each world in our Solar System is unique. When we compare them, the results are truly shocking.

All the stars, stellar corpses, planets, and other large, massive objects take on spherical or spheroidal shapes. Why is that universal?

If there’s life lurking on the moons of Saturn and Jupiter, could our instruments even detect it?

From the coldest planets to spacecraft that have exited the Solar System, these little-known facts stump even many professional astronomers.

The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.

For now, our Solar System’s eight planets are all safe, and relatively stable. Billions of years from now, everything will be different.

Can two planets stably share the same orbit? Conventional wisdom says no, but a look at Saturn’s moons might tell a different story.

The outer planets’ clouds hide the weirdness within.

Planets can be Earth-like or Neptune-like, but only rarely are in between. This hot, Saturn-like planet hints at a solution to this puzzle.

Many of us look at black holes as cosmic vacuum cleaners: sucking in everything in their vicinity. But it turns out they don’t suck at all.

The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it’s coming into focus better than ever before.

The secret ingredient is violence, and it just might indicate that “moonmoons” aren’t as uncommon as most astronomers think.

The recent discovery of a large cave on the Moon highlights the importance of caves not just for future space explorers but astrobiology as well.

Since the time of Galileo, Saturn’s rings have remained an unexplained mystery. A new idea may have finally solved the longstanding puzzle.

Despite the Sun’s high core temperatures, atomic nuclei repel each other too strongly to fuse together. Good thing for quantum physics!

The Schumann resonances are the background hum of the entire planet. But they don’t affect humans in any way.

Could life be widespread throughout the cosmos, in the subsurface oceans of ice-covered worlds? NASA’s Europa Clipper mission investigates.

MIT Scientist Jason Soderblom describes how the NASA mission will study the geology and composition of the surface of Jupiter’s water-rich moon and assess its astrobiological potential.

It could cut the time needed to reach Mars in half.

Get ready for the most peculiar road trip that will help you understand the vastness and emptiness of the solar system — and Sweden.

For thousands of years, humanity had no idea how far away the stars were. In the 1600s, Newton, Huygens, and Hooke all claimed to get there.

Straddling the bounds of science and religion, Newton wondered who set the planets in motion. Astrophysics reveals the answer.

2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.

The 5th brightest star in our night sky is young, blue, and apparently devoid of massive planets. New JWST observations deepen the mystery.

Physicists have increasingly begun to view life as information-processing “states of matter” that require special consideration.

What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.

The James Webb Space Telescope viewed Neptune, our Solar System’s final planet, for the first time. Here’s what we saw, and what it means.
